The SoDepthBuffer class is a node used to control the GL depth buffer.
With this node you can control properties related to the OpenGL depth buffer in a variety of ways.
The value range setting is useful if you need to segment the 3D world into different segments with different depth buffer resolutions to get a more optimal depth buffer resolution distribution than what a single, uniform depth buffer value range can give you.
Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
Enumeration for the various depth functions.
SoDepthBuffer::SoDepthBuffer | ( | void | ) |
Constructor.
SoDepthBuffer::~SoDepthBuffer | ( | ) | [protected, virtual] |
Destructor.
void SoDepthBuffer::initClass | ( | void | ) | [static] |
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoNode.
void SoDepthBuffer::GLRender | ( | SoGLRenderAction * | action | ) | [virtual] |
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoNode.
Enable depth buffer testing. Defaults to TRUE.
Enable depth buffer writing. Defaults to TRUE.
Which depth function to use. Defaults to LESS.
The value range for the depth buffer data. Defaults to [0.0-1.0]. The range will be clamped to [0.0-1.0].
